Why does my dog leak urine when it gets excited?

A dog leaking urine when excited is a normal physiological reaction, because puppies have poor control ability, so when emotions like excitement, nervousness, or fear run high, their bladder muscles contract and they involuntarily leak urine; generally they learn control after growing up. To reduce leaking, reduce emotional stimulation and don’t let the dog get too excited. Also appropriately increase the dog’s exercise, often taking it for walks and play to burn off excess energy. Finally, you can appropriately train the dog – when it gets excited, use a command to make it sit or shake hands, thereby diverting its attention.
